TOTO ST243ER#01 – Frequently Asked Questions
1) Which TOTO bowls does the ST243ER#01 Entrada tank fit?
The Entrada ST243ER#01 tank is made to pair with the TOTO Entrada C243EF or C244EF 1.28 GPF bowl. It is not a universal tank, so if the bowl in the room is a different TOTO model or another brand, this is the wrong tank for it.
2) Is the trip lever on this Entrada tank on the left or right side?
Right-hand side, and it ships with a chrome lever already on the tank. If the stall or vanity layout puts the wall on the right and you need the lever facing the other way, you need the left-hand version of the tank instead.
3) What comes in the box with the TOTO ST243ER#01 tank, and what else do I need to buy to finish the install?
The tank arrives with the tank-to-bowl gasket, tank-to-bowl hardware, and toilet bolt caps. Everything else for a complete installation is separate: the bowl, wax ring, floor mounting bolts, water supply line, and the seat. Worth staging those before the plumber is on site, because a tank-only order will not set a toilet.
4) Does this TOTO Entrada tank meet California water efficiency rules for a commercial restroom?
Yes. At 1.28 gallons per flush the Entrada tank is WaterSense labeled and meets both California CEC and CALGreen requirements, which is what most California spec sheets and rebate programs ask for on a new or replacement toilet.
5) Can I order just the tank to replace a cracked one and keep the existing bowl?
Yes, that is exactly what the ST243ER#01 is for. It is the tank only, in vitreous china, and it reuses nothing from the old tank because the gasket, tank-to-bowl bolts, and bolt caps come with it. The catch is the bowl underneath has to be an Entrada C243EF or C244EF.
6) Does this tank need batteries or any power at the fixture?
No power and no batteries. The Entrada tank is a straight gravity E-Max tank with a manual chrome trip lever, so there is nothing electrical to rough in.
